317 vs. 243 Does anyone run 317 heads (Truck 6.0) N/A with good luck? (BTW these are the aluminum ones, I think they also made steel 317's.) I know guys that use them with boosted applications due to the lower comp., approx 9.4:1. I have an LQ4 with torquer3 cam and a set of heavily ported 317's sitting on my work bench. A pretty knowledgeable friend of mine has a set of p/p 243's he would sell to me, and says they would work much better since they would be appox 10.4:1. I appriciate any advice on this.

Thanks for your time! I have had some SBC's that put me into mid 11's with 100 shot in my '53 Chevy truck....but now I have this lq4 sitting in it and I am new to these engines. These are lightyears ahead of the SBC, it is amazing how much power you can make with one reliably and on pump gas. Thanks again,

I hear ya on SBC, my dad has a 76 vett (350ci SBC) he did a body off restoration on, and thought I was full of **** about how much more power the ls1 had VS SBC. It took about 3 gears on his first ride in my car to humble to the old man alittle. Good luck with the lq4 and you might want to throw that 100 shot on it when you get it all dialed it
